The D-50H is VHT’s take on an extremely rare and iconic boutique amplifier. Handwired on eyelet boards, like VHT’s Special series amplifiers, the D-50H has three 12AX7 preamps and two Ruby Tubes 6L6GC output tubes. The D-50H has a single input, a three-way bright switch, a mid-boost switch and a jazz/rock voicing switch. Its unique treble, middle and bass controls provide a wide range of tone-shaping options.
